I found Lucy in HW to be a nice lady... not my cup of tea and so it was quite an eye opener!

I'm not quite sure if your post is a recommendation for Lucy, but I have seen her a couple of times and definitely recommend, although I reckon she probably only took me to (her) levels 1 or 2, she was great.
She has a glint in her eye, especially once she has you tied up, that I found a little scary but fun! She pushed my boundaries (as asked) but I never felt like I had completely lost control. She had plenty of more extreme equipment if I had been braver
A fun punt for those wanting more than vanilla. I will definitely be going back fairly soon.
